Composting and Vermicomposting: How to Transform Organic Waste into High-Value Input

Composting and vermicomposting — biological processes of transforming organic waste into high-value fertilizers — are the foundations of soil nutrition in organic and regenerative agriculture. In Brazil, over 50% of urban solid waste is organic — and composting turns this environmental liability into a high-value agronomic asset.

Mature organic compost is the fertilizer with the greatest impact on soil health — with simultaneous effects on its physical (structure and water capacity), chemical (nutrient availability), and biological (microbial activity) properties. One ton of mature compost is worth R$ 200 to R$ 600 for organic growers — vs. R$ 20 to R$ 60 for raw waste.

When composting is carried out correctly and the final product is certified through analysis, this sector can greatly contribute to job and income generation in Brazil.

Join our strategic actions to implement the best solutions in the Brazilian agricultural sector. Our activities, studies, and advanced research cover 20 chains and 255 segments of the national agro — from grain chains to sustainable extraction, including horticulture, fruit growing, livestock, and much more.

The series Innovation for Brazil to Produce More was specifically developed to identify and implement the best available solutions in Brazil and worldwide, across the 255 segments of the agricultural sector — with accessible technical language, updated data, and a focus on practical results for producers, suppliers, governments, and traders.

1.  Opportunities for Small Rural Producers

How to structure quality composting for the organic fertilizer market

Quality composting begins with the correct C:N ratio of 25 to 35:1 — a mixture of carbon-rich materials (straw, sawdust) and nitrogen (manure, plant residues) in the right proportions for thermophilic fermentation (55 to 65°C) that eliminates pathogens and seeds.

✔    C:N ratio of 25 to 35:1 — mixture of carbonaceous and nitrogenous materials

✔    Temperature 55 to 65°C — thermophilic phase that eliminates pathogens

✔    Turning the pile every 7 to 14 days — oxygenation and homogenization

✔    Minimum maturation of 90 days — high-quality mature compost

✔    Analysis of N, P, K, and organic matter — certification for commercialization

The E-Book 01 — Strategic Manual for Small Rural Producers presents, in detail, the best solutions for this segment and the other 254 of the Brazilian agro — focusing on methods, cost reduction, and progressive growth from Agro 1.0 to Agro 6.0.   Access now for BRL 99.00 →

2.  Opportunities for Micro and Small Local Suppliers

What equipment do composting and vermicomposting require

Composting requires turners, sieves, and packagers — with investment ranging from R$ 5,000 to R$ 200,000 depending on the scale.

Solutions by engineering applied to the segment

Our activities, studies, and advanced research cover six major areas of engineering — and the sector demands solutions in all of them:

Electrical Engineering and Computing — automatic pile turners;

Electronic Engineering and IoT — temperature and humidity sensors for piles;

Control and Automation Engineering — compost aeration systems;

Mechatronics and Robotics Engineering — vibrating compost sieves;

Renewable Energy Engineering — solar for turners and packagers;

Data Science and Artificial Intelligence — batch management and certification.

✔    Turners for composting

✔    Vibrating compost sieves

✔    Chemical analysis of compost

✔    Big bag and bag packagers

✔    MAPA certification for organic compost

The E-Book 02 — Strategic Guide for Micro and Small Local Suppliers maps, segment by segment, the business opportunities — focusing on IoT, energy, automation, and specialized technical services.  Access now for BRL 99.00 →

3.  Opportunities for Municipal Governments

How municipalities can support composting and create a circular economy

Municipal composting transforms organic waste into fertilizer for school gardens — closing the circular economy cycle with public health and food production.

✔    Municipal composting unit for organic waste

✔    Municipal compost for school and community gardens

✔    Municipal IDM: locally composted organic waste

✔    Home composting program with worms

✔    Sale of municipal compost to local horticulturists

The E-Book 03 — Reference Guide for Municipal Governments presents a step-by-step guide for municipal secretaries and managers to implement effective public policies for the 255 segments of the agro.  Access now for BRL 99.00 →

4.  Opportunities for Small Agricultural Product Traders

How composting generates business for growers, municipalities, and the waste sector

The composting company that transforms waste from fairs and restaurants into certified compost for organic growers has revenue from two sides — charges R$ 50 to R$ 150/ton to receive the waste and sells R$ 200 to R$ 600/ton for mature compost.

For the organic grower, the certified compost with NPK analysis is the input with the greatest impact on the quality of vegetables — and the supplier of compost with analytical reports and regular delivery is the most strategic partner in the organic production cycle.

Products with high commercial potential

The main products derived from this segment for local retail and foodservice:

Certified mature organic compost— R$ 200 to R$ 600/ton;

Premium worm humus— R$ 3 to R$ 8/kg;

Liquid biofertilizer— high-value foliar product;

Composting of slaughterhouse waste— B2B in volume;

Consulting in municipal composting— a growing service;

Cooperative mini-composting plant— product for associations.

Trader profiles and their specific opportunities

✔    Composting companies: transformation of organic waste

✔    Organic growers: certified compost as a nutritional base

✔    Municipalities: composting for urban organic waste

✔    Agricultural cooperatives: compost for members

✔    Distributors: compost and humus for the gardening market

✔    Nurseries: compost substrate for seedlings

Growth strategies for local traders

The composting company that contracts with a supermarket chain for organic waste has guaranteed raw material at a negative cost and sells certified mature compost to growers — the most profitable circular economy model available in the organic waste sector.

The BNDES Fundo Verde and Pronampe cover composting. SEBRAE subsidizes MAPA certification.
